An association may exist between patients diagnosed with psoriasis and a higher frequency of indoor tanning use during one’s lifetime, according to a study data published in the British Journal of Dermatology.

In the study, investigators evaluated the frequency of indoor tanning in women with psoriasis using data acquired from the Nurses’ Health Study II. In this 2005 study, women responded to queries regarding tanning bed use frequency in high school or college, between ages 25 and 35, or during the past 2 years. Respondents indicated number of times per year they used indoor tanning, ranging from none to more than 24 times.
